Are you letting it warm up pretty good? these old cars are not like modern cars turn the key and go.
Did this car set for a long time? bad fuel/water in fuel?
It's after it has warmed up that it acts up. While it is cold it will scream the tires. It sat for about 3 months. I drained the fuel tank and put fresh gas in before I started it the first time. Also new fuel filter.
